No, as GRH doesn't know any more today, what prefixes where present
yesterday etc. This could be solved by having per-prefix a 'seen'/'not
seen' mark, whenever it toggles though.

You can look at the lookingglass (/tools/grh/lg/) to check how many
prefixes where announced at a certain date. This does not make the
missing ones visible though.

You might want to check RIS, as RIPE does have a large system for
historical data.
